Mango is an unimplemented programming language by User:RaiseAfloppaFan3925 inspired by modern 2010-20s slang.

Keywords

Here is a list of all of the keywords so far and what they do.

Keyword	Action	Note
21	Not a keyword, however if a 2 and a 1 are adjacent then the compiler prints 9 + 10 == 21	Example: vro x = 67; vro y = "67"; vro z = 6741; vro var67 = 21; Compiler output: 1:9: SIX SEVEN 2:10: SIX SEVEN 3:9: SIX SEVEN 3:11: 41 4:8: SIX SEVEN 4:13: 9 + 10 == 21
41	Not a keyword, however if a 4 and a 1 are adjacent then the compiler prints 41
67	Not a keyword, however if a 6 and a 7 are adjacent then the compiler prints SIX SEVEN
aight bet	try, must be paired with a bro tweaking fr	Unstable, may change soon
be	Equals sign in variable declaration and assignment Examples: vro x be 0; vro y be x + 1; x be y + 1; y be x - 1;
bro	Private class/structure member/property
bro tweaking fr	catch, must be paired with a aight bet	Unstable, may change soon
cap	false
clapback	Return statement
crash out	Throws an error/exception	Unstable, may change soon. Exceptions are not planned and may be scrapped in favor of things like Rust's Result<T, E> or something
diva	Declares a class/structure
eeffoc	continue statement in loops
It's giving	Comment.	Unstable, may change soon
mogged	Checks if the expression to the left is greater than the expression to the right, literally > Example: 7 mogged 3 sus { cap => yap("Skill issue"), no cap => yap("MOGGED"), }
mogged by	Opposite of mogged, so < Example: 7 mogged by 3 sus { cap => yap("cap"), no cap => yap("MOGGED"), }
moot	Defines a public class/structure member/property
moots	Checks if the two values are equal, like a moots b.
no cap	true
nt tuff	Same as so kevin	Raises a compile error if it's not followed by as much wilted rose (🥀) emojis as the column number that the nt tuff keyword starts at Example: It's giving the "nt tuff" keyword is at column 3 (1:3), so it has to be followed by 3 wilted rose emojis x nt tuff🥀🥀🥀 sus { no cap => yap("x is sus"), cap => yap("x is not sus"), }
so kevin	Append to the end of an expression to check if it's falsey Example: x so kevin sus { nocap => yap("x is false"), cap => yap("x is true"), }
so owen	Append to the end of an expression to check if it's truthy Example: x so owen sus { nocap => yap("x is true"), cap => yap("x is false"), }
so tuff	Append to an expression to check if it's truthy	Raises a compile error if it's not followed by as much of these emojis (❤️‍🩹 or 🌹)) Example: x so tuff❤️‍🩹❤️‍🩹❤️‍🩹 { nocap => yap("x is true"), cap => yap("x is false"), }
sus	Rust match expression
ts	self or this in "normal" programming languages	Unstable, may change soon
vro	Declares a variable or function	Unstable, may change soon

Example Programs

Hello World

vro main() {
    yap("Hello world");
}

Deadfish interpreter

vro main() {
    vro source be input("> ");

    vro acc be 0;

    for char in source {
        char sus {
            'i' => acc be acc + 1,
            'd' => acc be acc - 1,
            's' => acc be acc * acc,
            'o' => yap(acc),
            _ => eeffoc,
        }
    }
}

Stack

Note: Borrowed from the LOLCODE example

diva Stack {
    bro length be 0;
    bro capacity be 0;
    bro array be [];

    moot size {
        get => ts length,
    };

    moot top {
        get => clapback ts length moots 0 sus {
            no cap => crash out "Sussy baka", It's giving no stack top
            cap => ts array[ts length - 1],
        },
    };

    vro push(ts, value) {
        ts length + 1 mogged ts capacity sus {
            no cap => {
                It's giving idk if the language is low-level yet so we fake it
                vro old_capacity be ts capacity;
                vro new_capacity be ts capacity mogged 8 sus {
                    no cap => ts capacity * 2,
                    cap => 8,
                };
                array resize(new_capacity);
                ts capacity be new_capacity;
            }
        }

        ts array[ts length] be value;
        ts length be ts length + 1;
    }

    vro pop(ts) {
        ts length mogged 0 sus {
            cap {
                It's giving THE STACK IS EMPTY YOU CANNOT POP IT
                crash out "Sussy baka";
            }
        }

        ts length be ts length - 1;
        clapback ts array[ts length];
    }

    vro peek(ts) {
        ts length mogged 0 sus {
            cap => crash out "Sussy baka";
        }

        clapback ts array[ts length - 1];
    }
}

vro main() {
    vro pile giving Stack vibes;

    pile push("skibidi");
    pile push("toilet");

    yap(pile size); It's giving 2

    yap(pile peek());
    yap(pile top);

    yap(pile pop());
    yap(pile pop());

    yap(pile size); It's giving 0

    aight bet {
        yap(pile pop());
    } bro tweaking fr {
        yap("Nahh bro tweaking fr");
    }
}
